A 1,040 kg meteor strikes the surface of the Moon. What is the work done (in J) on the meteor by the gravitational field of the Moon, if we assume the meteor comes from deep space?
(a) How much work is done by the Moon's graviational field on a 1500 kg meteor as it comes in from outer space and impacts on the Moon's surface? 4.28785714e9 J Correct: Your answer is correct. (b) If the meteor hits the moon with a speed of 4.2 km/s, how fast was it moving in deep space?
A meteor from outer space strikes the Earth. Ignoring gravitational effects from other bodies in the solar system, and assuming that the meteor is initially at rest at a great distance from the Earth, what is the impact speed of the meteor?
A meteor strikes the moon (event A), causing a large and vivid explosion. Exactly 0.47 s later (as measured in an inertial reference frame attached to the earth), a radio telescope receiving signals from the moon goes on the fritz. Could these events be causally related? Explain.
Consider an object of mass 60 kg on the surface of the Moon, which has a mass of 7.3 x 1022 kg and a radius of 1740 km. Calculate the gravitational force experienced by the object due to the Moon Note: you may find the following information useful -- the universal gravitational constant is 6.67x10-11 Nm2/kg2 3.2 N 0 9.8 N O 11.6N O 588.0 N O 96.5 N
In order better to map the surface features of the Moon, a 359-kg imaging satellite is put into circular orbit around the Moon at an altitude of 1.31 ? 102 km. Calculate the satellite\'s kinetic energy, gravitational potential energy, and total orbital energy. The radius and mass of the Moon are 1.74 ? 103 km and 7.36 ? 1022 kg.
(a) Calculate the work done (in J) on a 1450 kg elevator car by its cable to lift it 39.0 m at constant speed, assuming friction averages 145 N (b) What is the work done (in J) on the lift by the gravitational force in this process? (c) What is the total work done (in 1) on the lift?
y(t) = yg +ve+-0.5gt Meteor! y = 7,000 km 1) Show that a meteor, initially at rest (V,0 = 0) will take about 20 minutes to fall from an altitude of 7,000 km as shown in the diagram to the right. Note that the change in y is negative and you will need to convert kom into meters for the units to work out correctly. y = 0 km R= 6,371 km The calculation from problem 1) is incorrect though....
At a certain instant, the earth, the moon, and a stationary 1500 kg spacecraft lie at the vertices of an equilateral triangle whose sides are 3.84×105km in length. A. Find the magnitude of the net gravitational force exerted on the spacecraft by the earth and moon. Express your answer to three significant figures. F=????N B. Find the direction of the net gravitational force exerted on the spacecraft by the earth and moon. State the direction as an angle measured from...
